In Device Setup…Cubase AI unable to recognize ASIO input. 
when clicking on marker it states “not recognized” and nothing else.
when clicking on marker ASIO outputs… it recognizes my “UR22” L&R line out"
Am I missing something???
Please shut down Cubase. Download and install the latest UR22 Tools from UR22 Updates and Downloads | Steinberg then restart your computer.
Reopen AI and open a new empty project. Are you able to set the connections here? If not, what version and build of Cubase AI is it? What operating system are you on? When did the problem start?
